I would need to double check if at this point gd->fdt_blob is in it's final state or might get updated afterwards. Actually I think we should change all RPi configs to OF_BOARD, which would also be necessary to implement a single binary for RPi3 and RPi4. But that's another story. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
